This study presents numerical simulations analysing the effect of urban heat island (UHI) mitigation measures on chemical composition atmosphere. The mesoscale transport model WRF-Chem is used to investigate impact greening and highly reflective surfaces concentrations primary (CO, NO) as well secondary pollutants (O3) inside canopy. In order account for sub-grid scale heterogeneity areas, a multi-layer canopy coupled WRF-Chem. Using this at its full extend requires introduction several land...
Abstract. It is hypothesized that more accurate prediction and warning of natural hazards, such as the impacts severe weather mediated through various components environment, require a integrated Earth System approach to forecasting. This hypothesis can be explored using regional coupled systems, in which known interactions feedbacks between different physical biogeochemical environment across sky, sea land simulated. Such systems are becoming increasingly common research tools. paper...
Abstract. This paper describes an updated configuration of the regional coupled research system, termed UKC3, developed and evaluated under UK Environmental Prediction collaboration. represents a further step towards vision simulating numerous interactions feedbacks between different physical biogeochemical components environment across sky, sea land using more integrated prediction systems at kilometre-scale resolution. The UKC3 system incorporates models atmosphere (Met Office Unified...
In 2050 the fraction of urban global population will increase to over 69 %, which means that around 6.3 billion people are expected live in areas (UN 2011). Cities predominant habitation places for humans and vulnerable extreme weather events aggravating phenomena like heat stress. Finding mitigation strategies sustain future development is great importance, given influences on human health. this study, mesoscale numerical model WRF used a regional scale area Stuttgart, simulate effect...

Climate sensitive urban planning involves the implementation of green infrastructure as one measure to mitigate excessive heat in areas. Depending on thermal conditions, certain trees tend emit more biogenic volatile organic compounds, which act precursors for ozone formation, thus hampering air quality. Combining a theoretical approach from box model analysis and microscale modeling microclimate ENVI-met, we analyze this relationship selected region Germany provide link quality prediction...
Climate friendly urban planning plays a key role in climate change mitigation and adaptation allows for sustainable development of living conditions future generations. It has been long understood that measures such as greening, planted facades roofs or highly reflecting building materials are able to dampen excess heat help reducing energetic costs. Transferring scientific often theoretical knowledge into actual however necessarily involves an interdisciplinary dialogue. This paper intends...
Results from high resolution 7-km WRF regional climate model (RCM) simulations are used to analyse changes in the occurrence frequencies of heat waves, precipitation extremes and duration winter time freezing period for highly populated urban areas Central Europe. The projected change impact is assessed 11 based on indices a future (2021–2050) compared reference (1971–2000) using IPCC AR4 A1B Scenario as boundary conditions. These calculated daily maximum, minimum mean temperatures well...
Sea‐surface temperature (SST) is a key driver for various interactions and feedbacks between components of the Earth System can control local weather climate. The formation marine fog, example, be sensitive to small changes in SST at scale few kilometres. As contribution understanding processes interface air sea, this article discusses results from state‐of‐the‐art fully coupled regional atmosphere–land–ocean–wave prediction system UK km scale. This study focuses on impact surface forcing...
Abstract This study presents a numerical simulation assessing the effect of dynamical ocean–atmosphere coupling on structure marine atmospheric boundary layer over southern North Sea. Using high‐resolution regional coupled ocean‐atmosphere prediction system, with frequency 1 h, diurnal variation sea surface temperature simulated by ocean model is applied to atmosphere component. results in warming compared an atmosphere‐only run. Shallow convection initiated heating lower relatively warmer...
Heat poses a significant risk to human health, particularly for vulnerable populations, such as pregnant women, older individuals, young children and people with pre-existing medical conditions. In view of this, we formulated heat stress-avoidant routing approach in Heidelberg, Germany, ensure mobility support day-to-day activities urban areas during events. Although the primary focus is on pedestrians, it also applicable cyclists. To obtain nuanced understanding needs demands wider...
In the course of Soil Moisture and Ocean Salinity (SMOS) mission calibration validation activities, a ground based L-band radiometer ELBARA II was situated at test site Puch in Southern Germany Upper Danube Catchment.

Abstract. We present high spatial resolution (up to 2.2×2.2 km2) simulations focussed over south-west Germany using the online coupled regional atmospheric chemistry model system MECO(n) (MESSy-fied ECHAM and COSMO models nested n times).
